PubSubClient.publish tries convert char into unsinged int and throws error

Asked 2022-Apr-04 at 11:21

First of all, I am a far cry from a being an experienced programmer, so please forgive me if I am asking beginners question here.

I encountered a problem trying to publish a payload using the PubSubClient on an ESP8266. I am using VS Code with Platformio.

During Build I receive the following error. It seems like the PubSubClient is trying to convert the payload from char to unsinged int, even though the payload is defined as const char in the API of the PubSubClient library.

Your mqttMessageCharArray is of type char[] (which decays to char* on passing to function), whereas your mqttClient->publish() takes a uint8_t* as its second argument.

It can simply be fixed by replacing the last line with :-

Use gcloud auth application-default login. That command create a JSON file in the "well-known" location and the Google Cloud client libraries are able to find the file and then to use your user credentials.

Of course, your user account must be granted on the services to be able to use them.

I'm having trouble setting up a webhook endpoint API directly from RevenueCat's documentation.

My code is almost exactly like from the documentation so I don't know why this error is being triggered, and I'm not experienced enough with this kind of stuff to fix the issue. Here is the error I'm getting:

I believe that the client library that I'm using, @google-cloud/pubsub, automatically extends the acknowledgement deadline. With the following changes, I'm able to override that behavior, and the messages are indeed resent after the original acknowledgement deadline:

ANSWER

Answered 2021-Nov-24 at 13:53

We cannot judge this without more information.

I had the same issue multiple times, and the reasons were :

The internet connectivity was poor for the client/server so it was reconnecting again and again.

When I was dealing with real-time applications, the number of connections was very high, and because of which the dead/weak connections were disconnecting automatically.
Don't know why but the connection goes weird if I connect my phone's wifi ( Only 1 specific phone ).

QUESTION

Cloud Run PubSub high latency

Asked 2021-Nov-22 at 04:23

I'm building a microservice application consisting of many microservices build with Node.js and running on Cloud Run. I use PubSub in several different ways:

For streaming data daily. The microservices responsible for gathering analytical data from different advertising services (Facebook Ads, LinkedIn Ads, etc.) use PubSub to stream data to a microservice responsible for uploading data to Google BigQuery. There also are services that stream a higher load of data (> 1 Gb) from CRMs and other services by splitting it into smaller chunks.
For messaging among microservices about different events that don't require an immediate response.

Earlier, I experienced some insignificant latency with PubSub. I know it's an open issue considering up to several seconds latency with low messages throughput. But in my case, we are talking about several minutes latency.

Also, I occasionally get an error message

Received error while publishing: Total timeout of API google.pubsub.v1.Publisher exceeded 60000 milliseconds before any response was received.

I this case a message is not sent at all or is highly delayed.

This is how my code looks like.

The problem was in my understanding of Cloud Run Container's lifecycle. I used to send HTTP response 202 while having PubSub working in the background. After sending the response, the container switched to the idling state, what looked like high latency in my logs.

So I got the following situation: I'm trying to publish data from an DHT11 sensor (sensor is working just fine) via mqtt to my broker.

Your code defines a username and password for the MQTT broker but never actually uses them. You need to pass them to the connect method or else they do nothing.
